Description

[Detailed Description of the Invention] This invention relates to a support structure for a cooler for automobile air conditioning.

As shown in FIGS. 1 and 2, the conventional support structure has brackets 3 protruding sideways from side plates 2 provided on both sides of a cooler 1, and vibration-proofing rubber 4 mounted on the brackets 3. In addition, the cooler 1 is fixed by a collar 5 and bolts 6 that pass horizontally through the vibration isolating rubber 4, and the following problems arise.

Since the bracket 3 protrudes laterally, it is often necessary to reduce the width of the cooler 1 when considering the structure around the cooler 1, installation workability, ease of replacement service in the market, etc. cannot secure sufficient effective area.

The cooler 1 is supported by the radiator support panel 7, but due to the tightening space for the bolts 6, etc., it may not be possible to install the cooler 1 unless the area is narrowed. cannot be secured sufficiently.

Since the cooler 1 is attached to the radiator support panel 7 relatively rigidly, there is a high possibility that the cooler 1 will also be severely damaged when the vehicle body is damaged in a collision accident or the like.

The anti-vibration rubber 4 is always in a compressed state, and the amount of compression is regulated by the collar 5, but in order to obtain the optimum anti-vibration state, the collar 5 should be changed depending on the vehicle type and cooler specifications. This is not desirable in terms of manufacturing cost parts management.

Furthermore, in another conventional example shown in FIG.
This bracket 8 is fixed with a bolt 6. The brackets 3 and 8 were connected by bolts 9, and the vibration isolating rubber 4 was tightened by both brackets 3 and 8. Therefore, the above-mentioned problems) to) also occurred in this conventional example.

This idea was devised to solve these conventional problems.It not only maximizes the effective area of the cooler, but also allows the use of a small number of parts to deal with various conditions. The objective is to provide a support structure that can minimize damage to the

The support structure according to this invention supports the cooler by engaging the shear pins protruding from the radiator support panel with the upper ends of both sides of the cooler, simplifying the configuration and preventing the cooler from coming off in the event of a collision. In addition, vibration isolating rubber is interposed between the shear pin, the upper radiator support panel, and the cooler, and the vibration isolating rubber is held without being tightened.

Next, one embodiment of the support structure according to this invention will be described based on the drawings.

4 to 7, side plates 2, 2 are provided at both ends of the cooler 1, and the cooler 1
are attached to the upper and lower radiator support panels 10 and the front cross member 11 in the side plates 2,2. A nut 12 is welded to the radiator support panel 10, and a bolt 13 is screwed into the nut 12.
An engaging member 14 is fixed to the upper surface of the panel 10 by bolts 13, and this engaging member 14 is provided with a shear pin 15 that projects downward.
The shear pin 15 is inserted into a through hole 16 vertically bored in the panel 10 and projects below the panel 10.

An engagement groove 17 is horizontally cut into the upper end of the side plate 2, and a vibration isolating rubber 18 that comes into contact with the lower surface of the panel 10 is fitted into the engagement groove 17. As shown in FIG. 6, the engagement groove 17 is
Narrow width portion 19 located at the upper end of the side plate 2
, and the wide part 20 below it, and the wide part 2
0 is cut deeper in the horizontal direction than the narrow portion 19. Further, the innermost portion 21 of the narrow width portion 19 is enlarged into an arc shape. The anti-vibration rubber 18 has a shape in which upper and lower coaxial disc-shaped parts 22, 22 are connected by a small diameter part (not shown), and one of the disc-shaped parts 22 is housed in the wide part 20. This prevents the vibration isolating rubber 18 from being pulled out upward. Anti-vibration rubber 18
The small diameter portion is pushed into the narrow width portion 19 while being reduced in diameter,
and expands at the innermost part 21, and the vibration isolating rubber 18
prevents it from being pulled out to the side. Anti-vibration rubber 18
An engagement hole 23 is formed from the upper end of the shear pin 15, and the shear pin 15 is fitted into the engagement hole 23. That is, the upper end of the cooler 1 is supported by the panel 10 via a shear pin 15 and a vibration isolating rubber 18. The shear pin 15 has a moderately low strength, and when a large impact is applied to the cooler 1 due to a collision or the like, it immediately breaks and releases the cooler 1.

A stud 24 projecting downward is provided at the lower end of the side plate 2, and an engagement hole 25 into which the stud 24 is inserted is bored in the front cross member 11. A vibration isolating rubber 26 is fitted into the stud 24, and this vibration isolating rubber 26 is fitted into the hole 23.
is interposed between the inner surface of the cooler 1 and the stud 24 and between the lower surface of the cooler 1 and the panel 11.

The support structure having such a configuration has the following effects.

Since the cooler 1 is supported vertically by the shear pins 15 and studs 24 without using a conventional bracket, the effective area of the cooler 1 can be maximized.

Since the shear pin 15 is used to release the cooler 1 when a large load is applied to the cooler 1, damage to the cooler 1 can be minimized in the event of a collision or the like.

Since the vibration isolating rubbers 18 and 26 are interposed between the cooler 1, the panel 10, and the cross member 11 without tightening bolts, various adjustments can be made by simply adjusting the height of the upper and lower ends of the side plate 2. Common anti-vibration rubber 18 for the conditions of
26 may be used.

As mentioned above, the support structure according to this invention supports the cooler by engaging the shear pins protruding from the radiator support panel with the upper ends of both sides of the cooler, which simplifies the configuration and prevents cooling in the event of a collision. Since the anti-vibration rubber is interposed between the shear pin and the upper radiator support panel and the cooler, and the anti-vibration rubber is held without tightening, the effective area of the cooler can be maximized. In addition, it has the excellent effect of being able to deal with various conditions with a small number of parts, and minimizing damage to the cooler in the event of a collision or the like.
